Abstract

A circuit and method for controlling a discharge lamp (1a, 1b) without auxiliary lamp(s) are disclosed in which the discharge lamp (1a, 1b) is controlled in a warmed-up arc discharge state when, e.g., power generation of a vehicular alternator is detected, the discharge lamp (1a, 1b) is transferred from the warmed-up discharge state to an illumination arc discharge state when, e.g., an inner temperature of the discharge lamp (1a, 1b) has arrived at a predetermined value, the control of warmed-up discharge state is abruptly carried out when, e.g., the inner temperature of the discharge lamp (1a, 1b) is below the predetermined temperature, and a time at which the discharge lamp (1a, 1b) is to be turned off is controlled according to the tube temperature in another discharge lamp to be turned on.
